Cooling Sub-System

The cooling sub-system is compromised of five 40x40x56mm dual rotor fans, two 40x40x28mm
power supply fans, a CPU air duct, and a PS / Electronics Bay Isolation Air Baffle. These
components are used to provide the necessary cooling and airflow to the system. A fan on the
processor heat sink is not necessary in this chassis.
In order to maintain the necessary airflow within the system, the air baffle, CPU air duct, and the
top cover need to be properly installed.
®
Note: The Intel Server Chassis SR1500 does not support redundant cooling. Should a fan fail,
the system should be powered down as soon as possible to replace the failed fan.

Five-Fan Module

A fan assembly consisting of five 40x40x56mm dual rotor multi-speed fans provides the primary
airflow for the system. Four of the dual rotor fans provide the primary cooling for the processors,
memory, second and third hard drive bays, and components in the low profile PCI zone. The
fifth dual rotor fan provides the primary cooling for the components in the full height PCI zone.
Removal and insertion of the fans and fan module is tool-less and provides for ease of
installation and serviceability. Fans are individually replaceable through a connection to the hot-
swap backplane. Neither the fan assembly nor the individual fans within it are hot-swappable.
The server must be turned off before any of the fans can be replaced.
Each dual rotor fan has a 10-pin wire harness which connects to the hot-swap backplane. Each
fan harness provides power and tachometer lines allowing the fans to be monitored
independently by Intel
